• All hose and hosing is in compliance with guideline MDG 41 and
MSHA regulations.
• This model of shearer is available with onboard filtration, dust
suppression spray bars, shearer clearers and ranging arm spray rings.
Health Monitoring
Mainframe – MF4
• A comprehensive health monitoring system is available, including oil
levels and temperatures, flows, pressures and vibration analysis.
• High structural integrity and absorption of all cutting and haulage
forces, providing maximum protection for all major units
• Maximum protection of electrical boxes, providing the highest level
of flameproof integrity
• Improved access for maintenance and ease of overhaul and repair
• Versatility of application due to fully modular construction
• Split mainframe, in case of transportation limitations
Machine Automation and Communication
Industry-leading Automation from the Pioneer of State-based Automation.
• This shearer has a state-of-the-art distributed automation system
for the control, monitoring and protection of the shearer. Its modular
design allows it to be configured to meet individual control needs,
from basic monitoring and protection to advanced automation and
data transmission.
• The PMC Evo-S control system with state-of-the-art Ethernet
communication and backup functionality allows the shearer to be
operated even if the overall control system is not functioning.
• The shearer is equipped with a state-of-the-art industry PC in a flame­
proof housing with plenty of computing power, allowing flexibility to
upgrade to future features such as condition monitoring.
• A Programmable Logic Controller (PLC) takes care of basic machine
control tasks, ensuring that coal is produced.
• Unlike competitor systems, the modularity of the longwall system
and control allow the longwall to operate in “fault-tolerant” mode,
even when there is a problem with the overall automation system.
• In other words, integrated automation does not prevent control via
individual PLC’s in order to keep production up and running.
• Levels of automation:
– Zone-based automation “Navigator 1”
– State-based shearer automation “Navigator 2”
– Integrated longwall automation with “Navigator 2 + 3”
– “Longwall Navigator” for improved face alignment and horizon control
Hydraulically Activated Top Guards
• This shearer can be equipped with hydraulically activated top guards
Electrical Control Box – ECB3
• This flameproof module contains the majority of the shearer electrical
control and power distribution components.
• High current carrying capacity of 500 amps and can accommodate
trailing cables up to 240 mm2 (9.45 in2).
• All internal chassis can be ‘bench built,’ tested and stored.
• Box contains various LV circuit breakers which can be reset through
the FLP cover, reducing downtime.
• An extremely powerful PMC Evo-S control system with state-of-the-art
Ethernet communication and backup functionality, this allows the shearer
to be operated even if the overall control system is not functioning.
• This unit also contains cutter motor contactors, circuit breakers,
control transformer, current monitoring, HV fuses, earth leakage
and both visible disconnects.
Haulage Transformer Box – HTB3
• This flameproof module contains the main 350 kVA haulage transformer,
power supplies, auxiliary transformer, drive system circuit breaker
and two 200 kW (268 hp), 600V AC inverter drives, with regenerative
braking module.
